SLIVER BALLING momma FiledJune l, 1933 2 Sheets-Sheet 2 Patented May 22, 1934 UNITED STATES PATENT OFFICE SLIVER BALLING MACHINE Application June 1, 1933, Serial No. 673,892 In Great Britain June 21, 1932 1 Claim.

This invention relates to sliver balling machines of the type in which the sliver ball or roll is wound on retractable arbor sections carried by pivoted arms jointly movable about a 5 common axis parallel to the axes of the arbor sections so as to swing upwards in the formation of the ball, as described, for example, in the specification of Letters Patent No. 1,791,076 dated 3rd February, 1931.

In the machine according to the invention the sliver ball is confined during its formation by non-rotatable cheek-plates, embraced by the arms, said cheek plates varying their position with variation of the position of the arms, and

being arranged to release the ball on retraction of the arbor sections.

The cheek plates are fixed to the arbor-carrying arms, being moved away from and towards one another with the arms.

For positioning the ball relatively to the cheek plates during retraction of the arbor sections we fix to a skid plate, down which the ball rolls on ejection, horns which serve to steady the ball and hold it square to the cheek plates while the arbor sections are being retracted.

In the accompanying drawings Fig. 1 is a side elevation and Fig. 2 a plan view as seen in the direction indicated by the arrow A (Fig. 1), drawn to a slightly different scale, of a sliver balling machine according to the invention.

Referring to Figs. 1 and 2, the arbor sections indicated at 1 are extended through the pivoted arms 2 and carry external to the arms small driven friction pulleys 3 which, for starting-up purposes, bear upon large driving friction pulleys 4 coaxial with the usual fluted driving roller (not shown). The pulleys 3 have approximately the diameter of the arbor sections 1, and the pulleys 4 are of practically the same diameter as the fluted driving roller.

Fixed to the arms 2 are cheek plates 6 which are embraced by the arms 2 and which move apart and towards one another jointly with the arms.

As shown, there are fitted to a skid plate 10, down which the sliver ball 8 rolls on ejection, horns 11 which serve to steady the ball 8, and hold it square to the cheek plates while the arbor sections 1 are being retracted.

The arms 2 are swung apart for ejection of the sliver ball 8 by means of mechanism indicated generally at 12 as described in the specification of the said Letters Patent.

What we claim is: I

A sliver balling machine comprising retractable arbor sections on which the ball is wound, pivoted arms carrying said arbor sections, said arms being jointly movable about a common axis parallel with the axes of said arbor sections, nonrotatable cheek-plates embraced by said arms and fixed one to each arm, said cheek-plates serving to confine the ball during its formation and releasing the ball on retraction of said arbor sections, a skid plate to receive the ball on ejection from between said cheek-plates, and horns fitted to said skid plate and adapted to steady the ball during retraction of said arbor sections.
